3rd
Step-by-step explanation:
MARK AS BRAINLEST!!
You got the first part right
The theoretical probability is related to 1/2. A coin toss should always come up heads 1/2 the time and tails one 1/2 the time. So out of a class of 40 people, 20 people should flip (say) heads in theory and the other half of a class of 40 should flip tails 20 times.
Put more formally it looks like this.
P(sample) = Sample size * P(of it occurring once)
P(of it occurring once) = 1/2
Sample size = 40
P(sample) = 40 * 1/2
P(sample) = 20
Answer:
m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)
Step-by-step explanation:
In the diagram. check attach image
m∠A + m∠B + m∠C + m∠D = 360º.
Every quadrilateral can be decomposed (cut apart) into two triangles, each of whose angles' measures sum to 180º.
m∠A + m∠1 + m∠ 3 = 180º
m∠C + m∠2 + m∠4 = 180º
m∠A+m∠1+m∠3+m∠C+m∠2+m∠4 = 360º
therefore :
m∠4= 360-(m∠A+m∠1+m∠3+m∠C+m∠2)
<span>Susanne is 16 years old.</span>
b = Bob's age
s = Susanne's age
d = Dakota's age
Bob's age is 4 times greater than Susanne's age:
b = 4s
Dakota is three years younger than Susanne:
d = s - 3
The sum of Bob's, Susanne's, and Dakota's ages is 93:
b + s + d = 93
solve these equations:
b = 4s
d = s - 3
b + s + d = 93
and get:
b = 64 years
s = 16 years
(remember that s = Susanne)
d = 13 years
